    Using the DragDropService in RadDock

    Overview The new docking framework introduces service-based semantic, which allows for granular and pluggable functionality per RadDock. Entire drag-and-drop functionality is handled by the registered DragDropService instance, which simply receives drag requests and instantiates the appropriate operation. The service is responsible for drop target hit-testing, displaying docking guides and docking hints as well as for processing user input while dragging is in progress. On the screen above, toolWindow3 instance is being dragged. The service has hit-tested the MainDocumentContainer as a drop anchor and the appropriate docking guide is displayed. The “Left” docking position is selected and the service “hints” the user...

    Using Interceptors with Ado.Net Data Services and Telerik OpenAccess ORM

    ADO.NET Data Services enables an application to intercept request messages so that you can add custom logic to an operation. You can use this custom logic to validate data that goes to the client or returns to be persisted on the server. You can also use it to modify and filter further the scope of a query request, or add in that way a custom authorization policy on a per request basis. Interception is performed by specially attributed methods in the data service. These methods are called by ADO.NET Data Services at the appropriate point in message processing. Interceptors cannot accept...

    Using the ObjectContainer in disconnected scenarios – Part 2

    How to get objects into the ObjectContainer? The ObjectContainer contains a closed world of instances, no reference is dangling and pointing out of the container. That means, the instance graph is contained completely in this 'workspace'. Of course, at some points the need arises to prune the graph, as otherwise the whole database content would need to be stored in the containers memory. This is no different to the connected IObjectScope, but in the scope, we can directly perform the loading of objects from the database (lazy loading). With the container, there is no connection to a database,...

    Using LinqPad with Telerik OpenAccess ORM

    LinqPad is a nice and popular query analyzer made to test LINQ queries: whether it is Linq To Sql, Linq to Objects or some other flavor, you will be able to play in a nice way with it. Sadly it does not support Telerik OpenAccess ORM out of the box. However we never said it is impossible – you just have to put some more pressure to it. So, the first step is of course to deploy Telerik OpenAccess ORM and LinqPad on your machine. Then do the following: a) Open LinqPad and press F4 to bring up the Advanced Query...

    LINQ Tip of the Week: Optimizing query execution by using parameterized queries

    This is the first post of the series that have the goal to help Telerik OpenAccess ORM users enhance their experience in Linq against OpenAccess persistent objects. The two areas where performance enhancement can be taken advantage of are reusing a Linq query from the query cache and altering the query in a way where bigger portions of it are executed on the server. Today we will share with you a tip about the first one. When a Linq query is requested for execution, the query goes through a step of compilation – where the Linq query expression tree...
